If a number of little droplets of water of surface tension `sigma` all of the same radius r combine to form a single drop of radius R and the energy released in converted into kinetic energy find the velocity acquired by the bigger drop.

If a number of litle of droplets of water of surface tension S, all of the same radius r combine to from a single drop of radius R and the energy relased is converted into kinetic energy. Find the velocity acquired by the bigger drop. If the energy relased in converted inot heat, find the rise in temperature.

Let n number of little droplets of water of surface tension S (dyne/cm), all of the same radius r cm combine to from a single drop of radius R heat, while using cgs system of units answer the following questions. If the radius of the big drop formed is made two times without any change in temperature then the work done is

Let n number of little droplets of water of surface tension S (dyne/cm), all of the same radius r cm combine to from a single drop of radius R heat, while using cgs system of units answer the following questions. The energy released is

Let n number of little droplets of water of surface tension S (dyne/cm), all of the same radius r cm combine to from a single drop of radius R heat, while using cgs system of units answer the following questions. If the whole energy released is taken by water drop fromed, then rise in temperature in .^(@)C is

n droplets of equal size and each of radius r coalesce to form a bigger drop of radius R. the energy liberated is equal to

A large number of liquid drops each of radius 'a' coalesce to form a single spherical drop of radish b. The energy released in the process is converted into kinetic energy of the big drops formed. The speed of big drop will be

n number of water droplets, each of radius r , coalese, to form a single drop of radius R . The rise in temperature d theta is

A large number of droplets, each of radius a, coalesce to form a bigger drop of radius b . Assume that the energy released in the process is converted into the kinetic energy of the drop. The velocity of the drop is sigma = surface tension, rho = density)

n small droplets of water, each of radius r, coalesce ot form a single drop of radius R. Find (i) Velocity acquired by bigger drop if all the energy released is converted into kinetic energy. (ii) Rise in temperature. Take, surface tension of water =sigma Mechanical equivalent of heat =Q
